Technical Field

The technical field of the invention is that of horology, more precisely that of display mechanisms.

Background

Display mechanisms are known in the prior art which have a movement contained in a plane and/or along a free axis, which results in a limitation of the information provided to the user.

Indeed, the indicator (in this case a pointer) cannot simultaneously provide other indications or information to the user than an indication of the phase of the moon, the date and/or the time, etc. In other words, the indicator cannot give two pieces of information at the same time.

Disclosure of Invention

The present invention proposes to overcome these drawbacks, in whole or in part, by a display mechanism, in particular for a watch, preferably belonging to the category of watches, comprising:

-at least one indicator member: the at least one indicator member is mounted for rotation about a first axis of rotation via the first portion and is configured to move relative to the dial so as to indicate a first piece of information; said at least one indicator member being mounted for rotation about a second axis of rotation intersecting said first axis of rotation and extending longitudinally along said at least one indicator member, and said at least one indicator member comprising at least one rotating element mounted for rotation about said second axis of rotation via a second portion so as to indicate a second piece of information;

-at least one drive member assembly: the at least one drive assembly comprises at least one first drive member and at least one second drive member: the at least one second drive member is arranged on and/or in the at least one rotary element and is driven by the at least one first drive member;

when the at least one indicator member is rotatable about the first axis of rotation, and/or when the at least one drive member is rotatable about the first axis of rotation, the at least one first drive member is configured to cooperate with the at least one second drive member in such a way that the at least one rotary element is driven into a rotary motion via the at least one second drive member.

By this arrangement, the indicator can rotate about two separate axes of the dial, the seconds, minutes or hours.

In other words, said at least one first driving member is integral with said dial, second hand, minute hand or hour hand, respectively.

With this arrangement, when the hands are movable about the first axis, the rotating element above the dial, in particular the scale, the second hand, the minute hand or the hour hand, rotates about the second axis.

According to one embodiment, the first portion is a bobbin (barrel) and/or the second portion is a second axis of rotation and extends longitudinally along the at least one indicator member.

By this arrangement, the pointer can be moved about the first axis via the bobbin, and/or the second part supports the rotating element.

According to an embodiment, the at least one drive member assembly is at least one gear assembly comprising at least one first gear member and at least one second gear member, at least one micro-bearing assembly comprising at least one first micro-bearing and at least one second micro-bearing, and/or at least one bearing assembly comprising at least one first bearing and at least one second bearing.

According to one embodiment, said at least one rotating element is a weight of said at least one indicator member, a weight of a second hand, a weight of a minute hand or a weight of an hour hand, and wherein said at least one indicator member is a body of a second hand, a body of a minute hand or a body of an hour hand.

With this arrangement, the weight of the indicator member can be rotated about two separate axes.

According to one embodiment, said at least one indicator member is a second hand, a minute hand or an hour hand.

According to one embodiment, the second axis of rotation is coplanar with the dial, and the first axis of rotation lies in a different plane than the second axis of rotation.

According to one embodiment, the at least one drive member assembly comprises a universal joint (universal joint) and at least one third drive member; the at least one third drive member is arranged at an end of the rotating element for driving the second hand, the minute hand or the hour hand around a first axis of rotation.

The above-described embodiments and variants can be used individually or in any possible technical combination.

Detailed Description

As shown in fig. 1, the present invention is in the form of a display mechanism 100 for a wristwatch, and more specifically, a display mechanism 100 for a wristwatch.

As shown in fig. 1, the display mechanism 100 may include at least one indicator member 110 and at least one drive mechanism assembly 120.

As shown in fig. 2, according to this embodiment, the indicator member 110 may be mounted for rotation about the first axis of rotation 101 via a first portion 103, which first portion 103 may act as a spool 103.

The first portion 103 or the bobbin is moved with respect to a scale, preferably with respect to the dial 105, on which dial 105, for example, a scale representative of the moon phases, the dates and/or the times can be presented, in other words the following scale: which represents hours, minutes, seconds, or any smaller division of seconds, such as hundredths of a second or other divisions of seconds. Further, such a scale may represent power reserve, tachometer (tachmeter), day of the week, month of the year, ecliptic, temperature, pressure, altitude, depth, weather forecast, time zone, or any other indication related to the user.

The indicator member 110 is also rotatable about the second axis of rotation 102. The second axis of rotation 102 may intersect and/or be perpendicular to the first axis of rotation 101, according to one embodiment, the second axis of rotation 102 may be coplanar with the scale (i.e., the dial 105), and the first axis of rotation 101 may be in a different plane than the second axis of rotation 102.

The second axis of rotation 102 extends longitudinally along the indicator member 110 and may be realized by a second portion 104 extending longitudinally along the indicator member 110. The indicator member 110 may also consist of a rotational element 111, which rotational element 111 may be mounted for rotation about the second rotational axis 102 via the second portion 104.

As described above, the display mechanism may also include a drive member assembly 120. As shown in fig. 2 to 5A, 5B and 5C, the drive assembly includes a first drive member 121 and a second drive member 122.

The second drive member 122 may be arranged on and/or in the at least one rotational element 111 and may be driven by the first drive member 121. The latter, in other words the first drive member 121, may be configured to cooperate with the second drive member 122 to drive the rotational element 111 in a rotational movement about the second rotational axis 102.

Indeed, the view of the mechanism in fig. 2 and the enlarged view of fig. 3 clearly show that the indicator member 110 is rotatable about said first axis of rotation 101, the second drive member 122 is engageable with the first drive member 121, and the first drive member 121 rotates the rotary element 111 about the second axis of rotation 102 when the indicator member 110 is rotated about the first axis of rotation 101. Thus, the rotational element 111 may comprise a piece of information which will gradually appear as the indicator member 110 is turned around the first rotational axis 101. Obviously, the rotating element 111 may also represent an object, an engraving and/or a miniature of the object containing the second piece of information. The hands of the dial, in other words the hands belonging to the dial with graduations or indications, can therefore rotate about two distinct axes and indicate two pieces of information that are clearly differentiated as such. The cross-sectional view shown in fig. 4 shows one example of the positions of the first and second drive members 121, 122.

Thus, the rotational speed of the rotary element 111 about the second axis of rotation 102 may be determined on the one hand by the position of the first and second drive members 121, 122 and on the other hand by the ratio (e.g. gear ratio) between the first and second drive members 121, 122. For example, the first drive member 121 may be integral with the scale of the dial 105, the second hand 106, the minute hand 107, or the hour hand 108 as described above, and/or the second drive member 122 may be integral with the hour hand 108, the minute hand 107, or the second hand 106, depending on whether the indicator member 110 is the second hand 106, the minute hand 107, or the hour hand 108.

Furthermore, depending on the position in which the rotating element can be placed, a counterweight 109 may be necessary in order to balance the unbalance created by the weight of the second hand 106, the minute hand 107 or the hour hand 108, when the indicator member 110 is the second hand 106, the minute hand 107 or the hour hand 108, respectively.

According to one embodiment, the rotating element may be placed on a weight 109 of the second hand 106, the minute hand 107 or the hour hand 108. Accordingly, the weight 109 of the pointer can rotate about the first rotation axis 101 and about the second rotation axis 102.

The drive member assembly 120 described above may be in the form of: a gear assembly comprising the first gear member 121 and the second gear member 122, a micro-bearing assembly comprising the first micro-bearing and the second micro-bearing, and/or a bearing assembly comprising the first bearing and the second bearing. In certain embodiments, the drive member assembly 120 may be a universal joint, as shown in fig. 5A, 5B, and 5C.

In this case, contrary to the previous paragraph, it is the first drive member 121 that is rotatable about the first axis of rotation 101, instead of the indicator member 110. In fact, when the first part 103 of the gimbal rotates about the first rotation axis 101, the second part 104, in other words the rotational element 111, rotates about the second rotation axis 102, but not about the first rotation axis 101.

In this embodiment, the drive member assembly may further comprise at least one third drive member 123, which third drive member 123 may for example be arranged at an end of the rotating element 110, as shown in fig. 5A, in order to drive said second hand 106, said minute hand 107 or said hour hand 108 in rotation about the first rotation axis 101, while the universal joint rotates the rotating element 110 about the second rotation axis 102.

In other words, the rotary element 110 only moves around the second rotation axis 102. If an additional movement is desired, it may be necessary to add at least one third drive member 123 such that, when the first drive member 121 is rotatable about the first axis of rotation 101, the second drive member 122 and, according to one embodiment, the rotary element 111, rotates about the second axis of rotation 102, and the third drive member 123 rotates the rotary element 111 about the first axis of rotation 101. Thus, the rotating element 111 may comprise a second piece of information which will gradually appear when the indicator member 110 is rotated around the first rotation axis 101 and indicates the first piece of information.
